Answer

Adverse possession is the legal principle that someone occupying land without permission, openly and continuously for long enough, can eventually become its owner. It is real, it is much harder than the popular version suggests, and it is not the same thing as squatting in a house, which is a criminal offence.

The criminal position first, because this is the source of most confusion. Squatting in a residential building is a criminal offence in England and Wales — police can act, and no adverse possession claim can succeed through it, since the possession is unlawful in a way that defeats the claim. Squatting in non-residential property is not itself criminal, and is dealt with as a civil matter.

What an adverse possession claim actually requires:

Factual possession — genuine physical control, usually demonstrated by enclosure, fencing, maintenance or exclusive use.

Intention to possess the land to the exclusion of all others, including the paper owner.

Without the owner's permission. This is the one that defeats most claims: if the owner ever gave permission, even informally, the clock does not run. A licence, however casual, is fatal to a claim.

Continuity, without interruption, for the required period.

The registered land regime changed everything. For registered land, after ten years an applicant may apply — but the registrar then notifies the registered owner, who can simply object. An objection defeats the application unless narrow conditions apply, and the owner then has two years to act. In practice this made claims against registered land very difficult, which was the intention.

Unregistered land still follows the older twelve-year rule, which is why most successful claims concern unregistered or forgotten parcels.

Where it genuinely arises, and it is rarely dramatic: boundary disputes, where a fence was put in the wrong place decades ago and the land behind it has been used ever since; strips of access land; garden extensions; and forgotten parcels with no traceable owner.

What an owner should do: register the land, inspect it, and grant written permission where someone is using it.
